Description

Assembled hollow superstructure Technical Field The utility model relates to the technical field of hollow floors, in particular to an assembled hollow floor. Background The assembled hollow floor system is a building structure form combining prefabricated components and the hollow floor system technology. The core is that the hollow holes are arranged in the floor system, so that the concrete consumption is reduced, and meanwhile, the assembly type construction method is adopted, so that the construction efficiency is improved. Because the existing hollow floor slab concrete hollow floor slab technology adopts core mould pore-forming, a plurality of core mould arrays are required to be placed between two layers of reinforcing steel bar meshes in the construction process, each core mould is bound and fixed by steel wires, in the actual operation process, constructors cannot accurately grasp the distance between two adjacent core moulds, and in the binding process, the whole operation is time-consuming and labor-consuming, and the labor intensity of workers is increased, therefore, the assembled hollow floor slab is required to be provided, and the problems are solved. Disclosure of utility model In order to overcome the defects in the prior art, the utility model provides an assembled hollow building cover, which solves the problems mentioned in the background. The utility model provides a technical scheme that the assembled hollow floor comprises an assembled floor body, wherein connecting steel bars are arranged on the periphery of the assembled floor body, a positioning assembly is arranged in the assembled floor body, and a core mold is arranged on the positioning assembly; The positioning assembly comprises an upper guide rail strip and a lower guide rail strip, the upper guide rail strip and the lower guide rail strip are parallel and oppositely arranged, and the core die is arranged between the upper guide rail strip and the lower guide rail strip. Preferably, the positioning assembly further comprises a belt Kong Tuer, a limiting baffle frame and a pin shaft, a plurality of strip-shaped openings are formed in the upper guide rail strip and the lower guide rail strip at equal distances, and the lugs with holes are fixedly arranged at two ends of two sides of the strip-shaped openings. Preferably, the pin shafts are rotatably arranged at two ends of the limiting baffle frame, and the front ends of the outer surfaces of the pin shafts are provided with external threads. Preferably, the front end of the pin shaft is connected with a nut member through external threads, and the limiting baffle frame is rotationally connected with the lug with the hole through the pin shaft. Preferably, the upper guide rail strip and the lower guide rail strip are provided with avoiding notches matched with the nut pieces. Preferably, limit notches are formed in the centers of the upper surface and the lower surface of the core mold. Preferably, the end faces of one side, away from each other, of the upper guide rail strip and the lower guide rail strip are provided with cushion blocks. Preferably, the upper guide rail strip and the lower guide rail strip are both provided with supporting frames through cushion blocks at both ends. Compared with the prior art, the utility model has the following beneficial effects: 1. This assembled hollow superstructure, through being provided with locating component, initially, spacing frame that keeps off is in the horizontality, put next spacing frame that keeps off in advance, and then block into the mandrel one by one between last rail and lower rail, after every block into a mandrel, then just rotate the nut spare that is located spacing frame front end and take off the round pin axle for spacing frame rotatable to vertical state, and then will follow the round pin axle that takes off from last rail and pass foraminiferous lug and spacing frame lower extreme perforation on the lower rail, screw nut spare at last, realize that every mandrel all is in between two spacing frames, interval equals between two adjacent mandrels and can not back-and-forth movement, whole easy operation, labour saving and time saving. 2. According to the assembled hollow floor system, the limiting notch is formed, when the protruding parts of the upper guide rail strip and the lower guide rail strip are clamped into the limiting notch, the limiting effect on the core mould can be effectively achieved, the core mould is prevented from moving leftwards and rightwards horizontally, and the supporting frame can effectively support and fix the upper guide rail strip and the lower guide rail strip.
